Quick Lock Dumbbell 165lb Kit

If the Ironmaster Kettlebell Handle didn’t finish the argument, then this Custom Add on Kit surely will. The Ironmaster Quick-Lock Dumbbells land a knockout blow in the battle for the title of the best adjustable dumbbell.

I am the first to agree that there are dumbbells that are easier to change and look prettier, but if you are into serious weight training you are going to be after something that is made out of real steel and iron. This custom addon kit proves just how tough the Ironmaster dumbbells are.

To provide extra strength in the upper weight range, the custom addon screws are fully threaded. It will take longer than normal to make weight changes, but when you are lifting this heavy you won’t be moving through your workout at a cracking pace.

The Ironmaster Custom Add on Kit includes four custom locking screws and four 22.5lb plates. The Ironmaster Quick-Lock Dumbbells and Ironmaster Add On Kit are both sold separately. You need both of these sets to use the Custom Kit.

The Ironmaster Quick-Lock Dumbbell handles were designed for use with 120lb. So the 165lb Add On Kit will void the original warranty if the dumbbells are dropped or abused. Ironmaster have been selling these kits for many years and were previously only made available on request. So they have been tried and tested by some hardcore trainers.
